Caret Position SelectionStart, Simple?

This should be simple...

I have a maskedtextbox on a form, and I've added an OnEnter event which I want to set the caret position to zero (it defaults to the end). From what I've read you should use the SelectionStart Property to do this, but I can't get it to work. In the debugger it seems to reflect the correct selectionStart position but even though I set the value the caret doesn't get repositioned. I've also tried setting the selection length to various numbers along with the selectionStart...

Any help would be greatly appreciated.

Try this:

maskedTextBox.Select(0,0);

I've gotta be doing something wrong. This is driving me crazy!

This didn't work, I stepped through the debugger to make sure the event is being fired but sure enough it fires correctly but the position isn't set. Again, I just have an onEnter event on the control, which has maskedTextBox.select(0,0); I am tabbing over to the control to fire the event... I am doing something wrong?

private void maskedTextBox1_Enter(object sender, EventArgs e)

{

this.maskedTextBox1.Select(0,0);

}

Here is my code... The control IS being hosted by a usercontrol...if that matters. After this event fires the caret is still positioned at the end. I am using a mask...I'm not sure if that matters.

Help!

It works fine with me....... I dont know why its not workign for you. Try it in a seperate application, Use TextBox on Form and then on UserControl see behaviors.

I hope this will work!!!

Cheers ;-)

Hmmm. Ok, yeah I'll do that. Sounds to me like it should work. Have you tried hosting the maskedtextbox in a usercontrol? Maybe thats the problem. I will test out both myself tomorrow morning and repost. Thanks for your response!

No I've not tried in UserControl and left this job on you coz didnot have much time. And tell me what are the results.

Problem seems to be when you add a mask. If there is no mask, the caret gets put back to 0, if there is a mask, then the caret stays at the end. Anyone know how to work around this?

True, I didnot add any mask and did not test it with Mask, I'll check it when I have timie tomorrow.

I wish your problem is solved soon.

Thanks for your time RizwanSharp, apparently you can use the beginInvoke method to set the StartSelection when you have a mask.

Ahh, I'll remember this. But this is seemed some type of bug observe the meaning of two things Select(0,0); and SelectionStart = 0, The other thing BeginInvoke has some different purpose.

Anyhow, your problem is solved! i'm happy for that!
